Coronary heart disease (or coronary artery disease) is a narrowing of the small blood vessels that supply blood and oxygen to the heart (coronary arteries). Coronary disease usually results from the build-up of fatty material and plaque ( atherosclerosis) . As the coronary arteries narrow, the flow of blood to the heart can slow or stop, causing chest pain ( stable angina ), shortness of breath, heart attack , or other symptoms.

|
Coronary artery disease is a narrowing or blockage of the arteries and vessels that provide oxygen and nutrients to the heart. It is caused by atherosclerosis , an accumulation of fatty materials on the inner linings of arteries.
|
|
|
Coronary artery disease is a stenosis (narrowing) or blockage of the arteries and vessels that provide oxygenated blood to the heart . It is caused by atherosclerosis (hardening of the arteries), an accumulation of fatty plaque on the inner linings of arteries.

The heart, a powerful muscle that beats over 50,000 times in one day, is fed the blood and energy it needs through small tubes called coronary arteries (see Figure 1). Coronary artery disease (CAD) is the most common cause of death and disability in the United States and other industrialized countries, and it can be manifested if these arteries become narrowed by cholesterol to about half their normal diameter (see Figure 2).
|
|
|
Coronary artery bypass surgery creates a path for blood to flow around a blockage and helps prevent a heart attack.
|
|
|
Atherectomy is a procedure that relieves symptoms of coronary artery disease by improving blood flow to your heart.

A heart attack (myocardial infarction) occurs when an area of heart muscle dies or is permanently damaged because of an inadequate supply of oxygen to that area.
|
|
|
A heart attack is the death of, or damage to, part of the heart muscle because its blood supply is severely reduced or stopped. Heart attack is the leading cause of death in the United States.
|
|
|
A heart attack is an urgent message from your heart that it’s starved for oxygen. When oxygen-rich blood to your heart is blocked by a clot, heart muscle begins to die and symptoms of a heart attack start.

Hypertension is the term doctors use for high blood pressure. Blood pressure readings are measured in millimeters of mercury (mmHg) and usually given as 2 numbers. For example, 140 over 90 (written as 140/90. The top number is your systolic pressure, the pressure created when your heart beats. It is considered high if it is consistently over 140; The bottom number is your diastolic pressure, the pressure inside blood vessels when the heart is at rest. It is considered high if it is consistently over 90. Either or both of these numbers may be too high. Pre-hypertension is when your systolic blood pressure is between 120 and 139 or your diastolic blood pressure is between 80 and 89 on multiple readings. If you have pre-hypertension, you are more likely to develop high blood pressure at some point. See also: Blood pressure

Blood pressure is the force with which blood pushes against the artery walls as it travels through the body. Like air in a balloon, blood fills arteries to a certain capacity- and just as too much air pressure can cause damage to a balloon, too much blood pressure can harm healthy arteries.
|
|
|
Also known as high blood pressure, a condition in which too much force is exerted by the blood as it travels through the body ' s arteries. There are two types of hypertension: primary and secondary.
|
|
|
Each day that your blood pressure is too high, your chances of having a stroke are increased.
|
|
|
Hypertension is the medical term for high blood pressure. Blood pressure is the force of blood pushing against the walls of arteries as it flows through them.
|
|
The National High Blood Pressure Education Program (NHBPEP) was established in 1972 by the National Institute of Health to translate research results on the health hazards of high blood pressure into clinical and public health practice. Before 1900, high blood pressure, or hypertension, was not generally recognized as a health problem.
|
|
|
High blood pressure (hypertension) is called the silent killer. This is because many people who have it don’t know it. You can take an easy test to see if your blood pressure is too high. If it is high, you can take steps to lower it. Doing so could save your life.

Hyperthyroidism is an imbalance of metabolism caused by overproduction of thyroid hormone.
|
|
|
When you have hypothyroidism, your thyroid gland doesn’t produce enough hormone. With hyperthyroidism, the thyroid gland produces too much hormone. A goiter is the enlargement of the thyroid gland.
|
|
Hyperthyroidism is the condition that reflects excessive concentrations of thyroid hormones, due to any cause. The resulting hypermetabolic state causes increased heat production and accelerates many of the bodies ' processes.
|
|
|
Hyperthyroidism is the overproduction of thyroid hormones by an overactive thyroid. The term hyperthyroidism covers any disease which results in overabundance of thyroid hormone.
|
|
|
Hyperthyroidism is the overproduction of thyroid hormones by an overactive thyroid. Located in the front of the neck, the thyroid gland produces the hormones thyroxine (T 4 ) and triiodothyro-nine (T 3 ) that regulate the body ' s metabolic rate by helping to form protein ribonucleic acid (RNA) and increasing oxygen absorption in every cell.

Pericarditis is a disorder caused by inflammation of the pericardium, which is the sac-like covering of the heart.
|
|
|
Pericarditis is an inflammation of the two layers of the thin, sac-like membrane that surrounds the heart. This membrane is called the pericardium, so the term pericarditis means inflammation of the pericardium.

Stress can come from any situation or thought that makes you feel frustrated, angry, or anxious. What is stressful to one person is not necessarily stressful to another. Anxiety is a feeling of apprehension or fear. The source of this uneasiness is not always known or recognized, which can add to the distress you feel.
|
|
Stress is defined as an organism ' s total response to environmental demands or pressures. When stress was first studied in the 1950s, the term was used to denote both the causes and the experienced effects of these pressures.
|
|
Disturbance in the physiology of the individual. Among psychologists and psychiatrists, stress refers to a psychological reaction within the person to events that generate strong emotion that cannot be easily regulated; for other social scientists, the term stress is used to describe a disturbance in the individual ' s physiology.

Ways to manage stress: Get enough sleep, follow a healthy diet and make time for yourself.
|
|
|
Lower your risk: Control stress. When you’re stressed, your heartbeat speeds up and your blood pressure skyrockets. The next time you feel tension taking over, sit back and look at what’s bothering you.

Definitions Stress is a term that refers to the sum of the physical, mental, and emotional strains or tensions on a person. Feelings of stress in humans result from interactions between persons and their environment that are perceived as straining or exceeding their adaptive capacities and threatening their well-being.
|
|
Over the course of evolution, the human mind and body have developed means of handling stressful situations. Over the short term, such stress response pathways are highly adaptive, allowing a person to manage his or her resources in order to navigate the crisis; in some cases, however, these processes go awry and result in pathology.

Stress is an individual ' s physical and mental reaction to environmental demands or pressures. When stress was first studied, the term was used to denote both the causes and the experienced effects of these pressures.
|
|
Anything that brings on feelings of stress is called a stressor. Today, we often face many stressors.
